Oxidation of alkylphenylacetylenes and dialkylacetylenes on palladium catalysts in DMSO

Abstract

Alkylphenyl-and dialkylacetylenes are oxidized by the DMSO-PdCl₂ or DMSO-Pd/C system to give the corresponding 1,2-diketones. Oxidation of these compounds, unlike that of diarylacetylenes, is less selective and is accompanied by the partial cleavage of triple bonds and formation of ketones, 1,3-diketones, and aromatic compounds as secondary condensation products.
